Ironmaking

CISDI has strong capacity for research and development of new blast furnace process and techniques, as well as technology integration. It has gained intellectual property rights and accumulated much experience in the fields of engineering technology for large and medium sized blast furnace, and oversize blast furnace, in particular.

1. Blast Furnace System Integration
Integration of smelting technologies, plants, and control, management of modern blast furnaces, in addition to providing all-around solutions of engineering design, equipment manufacturing, installation, commissioning and startup, all help CISDI to obtain a long reference list of more than 140 blast furnaces at Baosteel, TISCO, etc.

7. Bell-less Top
CISDI has independently developed fully localized bell-less top technologies and core equipment with independent intellectual property rights. This kind of bell-less blast furnace top features compact structure, easy maintenance, blanking in the middle of the furnace, and even material distribution. Additionally, the bell-less top has been successfully applied to a 5000m3 blast furnace of Baosteel.

8. Blast Furnace Gas (BFG) Dry Dedusting
Compared with conventional wet dust removal, BFG dry dedusting has the advantages of cost saving, land efficiency, no water consumption, little pollution, low energy consumption, ideal purifying effect, and more. Also, it can make full use of the gas sensible heat and dry type TRT technology to produce more electricity.

9. TRT
CISDI started research and development off TRT technology since 1976 and supplied the engineering design and EPC services for the blast furnaces of Baosteel, Ansteel, NISCO, etc.
